ABSTRACT:
A portable cam actuated press which utilizes the substantial force available from an air spring to move a ram via the camming action of rollers mounted on the air spring, the ram, and on a frame into which all of the components are mounted. The substantial force available from an air spring and the specialty cam system provided allows the device to perform clinching, crimping, punching, stenciling, riveting, stamping or holding operations which would normally be performed with much larger and heavier equipment when the proper punches and dies are installed on the ram and into the frame cutout. The unit operates pneumatically without the need for hydraulics or hydraulically assisted components.
